For maintenance reasons, a penetration seal could bepermanently marked with an identification plate. In such acase, mark the identification plate fasten it in a visibleposition next to the seal.

Notice about approvalsCheck that the penetration has been sealed according tothe specified drawing in the UL Fire Resistance Directoryor Hilti Firestop Manual.
